• • 2. This comment has not been addressed. The ventilation in the area where the hood system is located is required to comply with IMC Section 403.3.1.1. Transcribing this comment into the construction drawings does not address the requirement. Note that the proposed placement in a storage closet is not acceptable;see comments below. Furthermore, this room is not anticipated to have ventilation complying with this requirement. Submit documentation substantiating compliance. See IMC Section 507.1 Exception 2. a. Response:Sheet M1.1—item 2—provides calculations as required in Section 403.3.1.1 of IMC 2018. Calculations show a requirement to provide 285 CFM of ventilation—the deign documents indicate that 300 CFM of ventilation will be provided. 3. This comment has not been addressed. The hood is required to comply with the minimum clearance requirements of IMC Sections 507.2.6 and 308.4. Documentation substantiating the minimum clearance requirements around the system should be submitted for review. The submitted documentation does not specify these clearances. In addition, the walls surrounding the appliance should be covered with a non-absorbent surface. a. IMC 507.2.6—Exception lwaives the 18" clearance requirement form combustibles when the appliance is adjacent to a minimum%:"gypsum wall board clad with a smooth, non-absorbent, non-combustible,washable surface. In this case the design calls for 5/8" gypsum wallboard clad with minimum 18 GA stainless steel. b. In addition to the wall protection described above,the wall cladding extends 18" beyond the footprint of the appliance in question and 24"above the top od said appliance. 4. This comment has not been completely addressed. Continuing with the previous comment, the system should be separated from the public by walls or other barriers to provide contact and injury. The proposed location of placing the appliance in a storage closet has been reviewed with the Fire Department and determined to not be an acceptable location for this appliance due to the high fire risk. The proposed location should be revised. A separate building permit is required where significant modifications to existing construction and or to construct new walls occurs. Minor modifications and wall construction may be included in the Type I hood application. Details including top and bottom wall anchorage should be included.See IBC Section 105.1 and IFC Section 104.1. a.

Response:Where the original documentation alluded to the space in question as a "storage space",the actual original use of the space was a kitchen.The present owner was not aware that the space was originally designed and possibly used as a kitchen—later becoming a storage space when the previous owner/tenant did not us the kitchen/scullery components. ii. The Overall Floor Plan on Sheet M-2.1 shows the following existing elements that are part of the kitchen:
